will not properly display under either a Linux Mint version 13 or version 14 installation ?

Every other page on this PDF will display correctly and even page 79 will display correctly if you page down to it one page at a time, however if you try go directly to page 79 by putting in page 79 of 108, it will not complete the display of the info for this page. I have also tried this with other PDF / tax forms on the IRS 1040 current year page and every other tax form, etc. that I opened displayed perfectly.

I have tried this very same thing (trying to get page 79 to display) on a CentOS 6.3 Linux installation and it displays perfectly every time.

If this is something to do with length of document, how come this does NOT happen on the document just ajacent/above the "general instructions", which includes all of the 1040 general instruction, PLUS all of the detailed instructions for the 1040 schedule forms, i.e. it is an even longer document than the "general instructions" and it does not happen on that document, i.e. I don't think this problem has anything to do with length/size of document.

I sort of found the resolution for this problem but I really don't understand why this is.

I went to the preferences in Firefox and then to applications and I noticed that the drop down setting for PDF file viewing was set by default to "PREVIEW IN FIREFOX".

I changed that setting to "USE DOCUMENT VIEWER DEFAULT" and re-tried the IRS instructions and that apparently fixed the problem because page 79 displayed correctly.

But what I don't understand is that the default viewer according to Firefox is ADOBE ACROBAT because the Adobe logo is shown beside the "USE DOCUMENT VIEWER DEFAULT" setting, HOWEVER when I go into Synaptic and search for Acroread, it shows that Acroread and related appllications are NOT installed.

Also, when I right hand click on a PDF file that I have in my home directory the default that is set for opening that PDF file is EVINCE not Adobe Acroread.

Can anyone tell me why that apparently Adobe Reader has been installed as the default document viewer by the OS installation and yet Evince is shown as the default viewer when doing a right click on an individual PDF file on the hard drive ?
